Figure 1 - Project Area Location The Project area is accessed from the Peak Downs Highway through the Carborough Downs and Broadlea Mines via an extension of existing haul roads. The Project area is situated within the Wotonga Pastoral Lease (cattle property) and is predominantly flat with sporadic rocky outcrops / hills. The land has been previously cleared for broad pasture cattle farming. Two ephemeral creek systems cross the Project area and flow during periods of heavy rain. 1.1 Objectives and Scope The objectives of this Initial Development Plan (IDP) are to: • provide an understanding of the nature and extent of the proposed development and production of mineral resources from the lease. • allow an assessment of the proposed development and whether it is appropriate with respect to the area, resource, state and people of Queensland. • assess the prospective resource utilisation and identify any resource sterilisation issues. • allow appropriate resource management decisions to be made. Page | 1 The scope of this IDP is based on the Development Plan and Work Program guide, by the Department of Natural Resources and Mines, 2016 (v1.02) and addresses, the following: • relevant legislative requirements for development plans • minerals that the Applicants’ will have the right to mine • maps and figures of the resource and mining proposals • states inter-relationship between multiple resources e.g. coal and coal seam gas 1.2 This Plan’s Period The period for this IDP is five years from the date of grant of the MLA. A Later Development Plan will be required to be submitted either within at least 40 business days before the end of the IDP period, or as soon as practicable after the Applicants propose a significant change to the nature and extent of the authorised activity that is not already dealt with under the IDP. 1.3 Legislative Requirements The requirements of the IDP are set out in Sections 318DT, 318DU, 318DV and 318DW of the Mineral Resources Act 1989 (MR Act), as detailed in Table 1 below. In preparing this IDP, the Applicants have relied on the guidance provided in the Development Plans and Work Programs (DNRM, 2014). Table 1 - Legislative Requirements This Document’s MLA Requirement Short Description Reference Overview of the activities during the term of the 318DT(1)(a) Section 2 / Section 3 ML The nature and extent of activities proposed for 318DT(1)(b)(i) Section 5 each year of the plan 318DT(1)(b)(ii) Where the activities are proposed Section 6 318DT(1)(c)(i) The location and estimate of the resource Section 7 Standards and procedures used to make

  • Bowen Basin Coalfields of Central Queensland (Figure 1)
    The South African Institute of Mining and Metallurgy International Symposium on Stability of Rock Slopes in Open Pit Mining and Civil Engineering John V Simmons and Peter J Simpson COMPOSITE FAILURE MECHANISMS IN COAL MEASURES ROCK MASSES – MYTHS AND REALITY John V Simmons Sherwood Geotechnical and Research Services Peter J Simpson BMA Coal Pty Ltd Central Queensland Office 1. INTRODUCTION Excavated slopes in open pit coal mines are designed to be as steep as possible consistent with stability and safety requirements. Slope failures occur for many reasons, including oversteepening. This paper is concerned with slope design and excavation experience in the Bowen Basin coalfields of central Queensland (Figure 1), Bowen Basin Coalfields Figure 1 Location of Bowen Basin open pit coal mines in eastern Australia Page 31 The South African Institute of Mining and Metallurgy International Symposium on Stability of Rock Slopes in Open Pit Mining and Civil Engineering John V Simmons and Peter J Simpson but it deals with many issues that are common to open pit coal mining generally. After more than three decades of operational experience and technological advances in the Bowen Basin mines, sudden rock slope failures still occur in circumstances where personnel and equipment are at extreme risk. The circumstances of a selection of these sudden failures are reviewed in this paper, and some concerning trends emerge. Classical structurally-controlled slope failures occur quite rarely in the Bowen Basin, but rock mass structures appear to exert important controls on the sudden failures that are more widely experienced. The term "composite" is used in this paper to describe failures involving combinations of intact rock material fracture and shear movement on defects (Baczynski, 2000).

  • Evaluation of the Gas Drainage Efficiency at the Grasstree Mine
    THE UNIVERSITY OF QUEENSLAND Bachelor of Engineering Thesis Evaluation of the Gas Drainage Efficiency at the Grasstree Mine Student Name: Michael VAN DER MEER Course Code: MINE4123 Supervisor: Associate Professor Mehmet Kizil and Doctor Saiied Aminossadati Submission date: 6 November, 2017 A thesis submitted in partial fulfilment of the requirements of the Bachelor of Engineering (Hons) degree in Mining Engineering (Extended Major) UQ Engineering Faculty of Engineering, Architecture and Information Technology i ABSTRACT Inappropriate coal mine gas management has the potential to cause catastrophic disasters resulting in multiple fatalities. Gas is naturally released into the mining work environment during production and development; pre- and post-drainage form the basis of gas management. The Grasstree Mine site located in the Bowen Basin is an underground coal mine that utilises both pre- and post-drainage techniques. Unique to Grasstree is the high gas content of the mining and adjacent seams. This project studies the methane capture efficiency of the GC906 longwall panel against critical events that affect the gas management and ventilation of the mine. The aim is to identify the most effective gas management techniques for future longwall blocks with reduced ventilation at the Grasstree Mine. The data utilised in this project was post-drainage flows and concentrations provided from measurements and recordings taken for the full duration of GC906 mining. Methane capture efficiency was calculated for each hour for the duration of GC906 longwall mining; 18/11/2016-21/06/2017. The critical events analysed were: Initial longwall square-up period; Transitioning from two to three return gateroads; Full duration of a HGH well transitioning from long to short goaf gas drainage; The restriction of a return roadway to improve goaf dynamics; and Analysis of the effects of vertical post-drainage holes over the maingate side on the overall gas drainage.

An extensive geotechnical database across the mine site area must be considered for mine planning and design. Some geotechnical parameters can be defined through the analysis of an appropriate suite of geophysical logs, including the acoustic scanner and sonic velocity logs and by incorporating a strict hybrid logging classification system. The acoustic scanner tool is becoming part of the standard geophysical logging suite used today in all stages of exploration drilling.

Given the The University of Queensland, Australia high cost of rehabilitation (AUD25 000/ha) and 2 Centre for Mined Land Rehabilitation, the relatively small areas involved, Grigg et al.

Guidelines for sustainable The development of improved pastures for cattle grazing management are therefore essential. grazing is a logical post-mining land-use option Long-term experience and research in for the Bowen Basin coalfields of central northern Australia have indicated that safe Queensland, but little is known of the potential stocking rates require that 30% or less of average productivity or livestock carrying capacity of seasonal pasture production is utilised (McKeon these systems.
